SECURE AND PRIVATE CONTENT DISTRIBUTION IN THE DRM ENVIRONMENT

Antonius Cahya Prihandoko, Hossein Ghodosi, Bruce Litow

Abstract.

Digital Rights Management (DRM) is required to provide balanced protection for both the content provider and the users in a content distribution system. The content provider demands secure content delivery so that only authorized users are able to access the content and use it properly. On the other hand, users require that their privacy be protected. However, most DRM systems tend to put greater emphasis on content providers’ security and neglect users’ privacy. This study aims to improve DRM by constructing a content distribution protocol that preserves the security of content provider and the privacy of users. To achieve this goal, we utilize the oblivious transfer (OT) concept. This concept allows a sender to securely send a set of information to a receiver in such a way that, at the end of the protocol, the receiver cannot learn more than he was supposed to learn, while the sender cannot determine what the receiver has learned. Assuming that tamper-proof device exists, the constructed protocol achieves perfect security for the content provider and privacy for the users. This oblivious content distribution ultimately enables DRM to be a privacy-aware protection system. The system does not merely focus on content providers’ rights, but also seriously considers users’ privacy protection.
